I wrote about this story, indirectly, a while back. Here's an excerpt:
A new story by Alice Munro in the current New Yorker had the Hound up part of the night, and just when she had begun to think that Munro couldn't zing her anymore. The twist in plot took her completely by surprise. Cheeky, it is. A smart rewrite of Flannery O'Connor's "A Good Man is Hard to Find," a story that has troubled more than one fiction writing class, and not only for its absolute darkness of vision (a fact O'Connor argues).
